SIDRA (Signalised Intersection Design and Research Aid) has been developed as a computer program to aid traffic engineers and researchers in their design and analysis of signalised intersections. This paper describes the facilities and use of SIDRA-2 which basically implements the techniques given int he Australian Road Research Board Report ARR no 123 together with additional advanced features. SIDRA-2 output is very extensive and includes: (1) listing of basic movement and intersection variables (flow ratios, lost times, degrees of saturation, etc); (2) estimates of movement saturation flows, capacities and spare capacities; (3) lane information (lane flows and saturation flows, effective green and red times, lane utilisation and operating characteristics); (4) computed signal timings and a signal timing diagram; (5) performance measures for computed or specified signal timings (delay, number of stops, queue length, fuel consumption, etc); and (6) separate summations for user-specified movement groupings such as pedestrians, buses, cars, major-and minor-road vehicles, etc. An example of both input data listing and output is given to illustrate the SIDRA method of estimating lane flows, capacities and operating characteristics. SIDRA-2 is now in use in traffic engineering practice and teaching in Australia and New Zealand. (TRRL)
